Help QEMU in deprecation of -drive if=none without the need to refactor all old boards. Stop masking out -blockdev support when -drive if=sd needs to be used. We achieve this by forbidding blockjobs and special-casing all other code paths. Blockjobs are sacrificed in this case as SD cards are a corner case for some ARM boards and are thus not used commonly. https://bugzilla.redhat.com/show_bug.cgi?id=1821692 Signed-off-by: Peter Krempa <pkrempa@xxxxxxxxxx> --- src/qemu/qemu_process.c | 9 --------- .../disk-arm-virtio-sd.aarch64-latest.args | 7 +++++-- 2 files changed, 5 insertions(+), 11 deletions(-) diff --git a/src/qemu/qemu_process.c b/src/qemu/qemu_process.c index b1751d4b52..dee3f3fb63 100644 --- a/src/qemu/qemu_process.c +++ b/src/qemu/qemu_process.c @@ -5488,7 +5488,6 @@ qemuProcessPrepareQEMUCaps(virDomainObjPtr vm, unsigned int processStartFlags) { qemuDomainObjPrivatePtr priv = vm->privateData; - size_t i; virObjectUnref(priv->qemuCaps); if (!(priv->qemuCaps = virQEMUCapsCacheLookupCopy(qemuCapsCache, @@ -5497,14 +5496,6 @@ qemuProcessPrepareQEMUCaps(virDomainObjPtr vm, vm->def->os.machine))) return -1; - /* clear the 'blockdev' capability for VMs which have disks that need -drive */ - for (i = 0; i < vm->def->ndisks; i++) { - if (qemuDiskBusIsSD(vm->def->disks[i]->bus)) { - virQEMUCapsClear(priv->qemuCaps, QEMU_CAPS_BLOCKDEV); - break; - } - } - if (processStartFlags & VIR_QEMU_PROCESS_START_STANDALONE) virQEMUCapsClear(priv->qemuCaps, QEMU_CAPS_CHARDEV_FD_PASS); diff --git a/tests/qemuxml2argvdata/disk-arm-virtio-sd.aarch64-latest.args b/tests/qemuxml2argvdata/disk-arm-virtio-sd.aarch64-latest.args index 7147dfee76..f17dd2157a 100644 --- a/tests/qemuxml2argvdata/disk-arm-virtio-sd.aarch64-latest.args +++ b/tests/qemuxml2argvdata/disk-arm-virtio-sd.aarch64-latest.args @@ -33,8 +33,11 @@ file=/tmp/lib/domain--1-armtest/master-key.aes \ -dtb /arm.dtb \ -usb \ -drive file=/arm-sd.qcow2,format=qcow2,if=sd,index=0 \ --drive file=/arm-virtio.qcow2,format=qcow2,if=none,id=drive-virtio-disk0 \ --device virtio-blk-device,scsi=off,drive=drive-virtio-disk0,id=virtio-disk0 \ +-blockdev '{"driver":"file","filename":"/arm-virtio.qcow2",\ +"node-name":"libvirt-1-storage","auto-read-only":true,"discard":"unmap"}' \ +-blockdev '{"node-name":"libvirt-1-format","read-only":false,"driver":"qcow2",\ +"file":"libvirt-1-storage"}' \ +-device virtio-blk-device,scsi=off,drive=libvirt-1-format,id=virtio-disk0 \ -sandbox on,obsolete=deny,elevateprivileges=deny,spawn=deny,\ resourcecontrol=deny \ -msg timestamp=on -- 2.26.2
